Application filed October 19, 1910. Serial No. 587,803.

To all whom it may 001 1061 12 Be it known that 1, JOHN L. MoHUN, a

.citizeu of the United States, residing at in the county of Kings and State new and useful Metallic Caris a specifica- Brooklyn, of New York, have invented Improvements in Flexible Roofs, of which the following tion.

This invention relates to metal roofs for cars, and has for one of its objects, to propole of the roof with a gutter or groove eX- tending longitudinally, for draining off any water that may collect therein.

Another object is to provide the metal roof sheets with edges, loosely supported at v the ridge pole and also along the carlines whereby a relative sliding movement may occur at these points, and greatly increase the flexibility of the roof;

Another object is to provide an improved drainage system in which any water that enters over the edges of the roof sheets may drain off through channels in the carlines.

Another object is to provide an improved ventilating means for permitting .a cireulation of air both from the interior of the car and through the channels in the carlines.

Another object is to provide improved means for supporting the running board extensions at the ends of the car.

Still another ob ect is to provide an unproved rain proof roof structure, which may bebuilt upof standard shapes and sections in all its parts, and-connected up in a cheap and simple manner, thereby avoiding allnecessity ofusing costly special parts and expensive skilled labor in its construction.

These'and other objects of my invention will hereinafter more fully appear from the following description and claims.

In the accompanying drawings: Figure 1 is a transverse sectional view of a portion of a car roof embodying certain features of -my improvements; Fig. 2, an .end view of a portion of the car and showing the running board and its extension; F ig. 3, a transverse connected I sectional view of a portion of the car roof showing a preferred construction for fastening the ends of the carlines to the side plates of the car; Fig. 1, a view at right angles to Fig. 3, the carline being indicated in transverse section; Fig. 5, a transverse section,

-upon a larger scale, of one form of my improved two-part metal carline, also showing the edges of the metal roof sheets supported between said parts; Fig. 6, a similar sec tional view illustrating a slight modification in which the roof sheet is provided with a lining; Fig. 7 a detail transverse section of the ridge pole and connections, taken through the flanges of a carline; Fig. 8, a side elevation of a portion of a car roof embodying my improvements; Fig. 9, a detail a carline connection point; Fig. 10, a side View of the same; Fig. 11, a transverse section of the ridge pole; Fig. 12, a plan of a portion of a purlin at a point where same is with a carline; Fig; 13, a side view of same; Fig. 14, a transverse section of a purlin; and, Figs. 15, 16, and 17, a side view, inverted plan, and transverse section, respectively, of the end portion of the cap member of a two-part carline.

According to the construction shown in the drawings, myimproved metal carlines are formed of two members; a main or lower member, 20, preferably constituted of pressed metal. such as steel, and containing a channel for draining off Water or moisture and discharging at the side of the-car, and an upper or cap member, 22.

The main or body portion of the carline is preferably formed of a trough or shaped section, as shown, the trough comprising the channel extending to the side of the car, and discharging over the side plate, 21, which may, if desired, be notched to receive the body portion of the carline.

The upper or cap member, 22, of the carline may be of any shape or section, but I prefer to form the same of a standard T section, the web of which extends down centrally into the trough between the walls of the U shaped body portion, 20, and is rigidly connected thereto by means of dowel pins, 35, preferably split and tapered so that the weight of the roof is carried by both members comprising'the two-part carlines. When the two members are thus secured together there is a sufiicient clearance between them to receive the edges of the metal Fatented Aug. 55,1913.

plan of a portion of the car ridge pole at roof sheets, 23, which are loosely supported,

so that there may be a sliding movement between said sheets and the members of the carline. The top flange of the cap section 22, of the carline, covers the trough or channel in the bodyportion, 20, and the side edges of the metalroofsheets, 23, extend over said channels and are preferably turned downward .sothat any water which enters under the cap section may readily drain into and through'said channel and be discharged over the side plates of the car. p I

The bodyfportion of-the carline, 20, is

preferably-formed with notches or recesses for receiving the'purlins, 24, and the ridge pole,'25, while the vertical web of the carline cap, 22, is notched orpartially cut away at these points to allow thetop flangeto'fit down closely and pass over the ridge and .purlins. In order to secure the parts of the} roof together at these points, the purlins and ridge pole may be provided with slots, 32, in

. their sides, to receive the edges of the vertical webs of the carline cap, whereby the framework. or'the supporting members of the roof, are, in a simple manner, keyed together without the use" of nails, bolts, or 'other fastening means in the purlins, and a strong but flexible roof structure is obtained.

This method 'of connecting the carlines and purlins also serves to center the cap member with reference to the main or body ortion of the carline.

I Other means may e employed for holding the cap member in a central position, such as'the spacing pieces,

26, which may be riveted upon opposite.

sides of the web of the cap member of the carline, as shownin Figs. 15, 16, 17. The web may be partially cut away or tapered down at the ends of the carlines, as shown in Fig. 3. v

At the car ridge, the edges of the roof sheets, 23, are supported upon the ridge pole,-

25, which is provided with a groove or gutter, 30, extending longitudinally and com-- municating through an opening, 31, with the channel in the body of the carline, the roof sheets being preferably turned down at the "edge, as shown, so as to drain into the ridge gutter and then out'through the carlines.

The gutter is covered by the ridge cap, 33,

which may be formed in sections extending between the'carlines, and having vent opentings spaced at any desired interval, the top flange of the carline cap, 22, passing over the ridge cap and holding the same securely in place,' as' shown more fully in Fig. 7.

Both the ridge pole and the purlins are.

preferably provided with shallow transverse recesses, 36, 'in their upper faces, at the .points where the top plate of the carline cap passes, and the down turned edges of the roof plates or sheets may be partially cut away or notched out to clear the purlins and ridge pole. Metallic lining-pieces, 37,-may

means of nails to the side and end plates, but

the otheredges of said sheets, along the carlines and at the ridge, are free to slide upon their supports. flexible construction, and provides for expansion and contraction ofthe roof and also .for't-he so-called weaving motion of the car.

As a means for fastening the carlinelbody to the side plates of the car, I have shown a bracket, 27, which may be of cast or pressed steel, and of such shape as to surround the Ushaped carline member and having flanges carline, the bracketbeing secured upon the inner face of-theside plate, 21, by means of This gives a very vertical bolts, 28, and a horizontal bolt, 29,

see Figs. 3 and 4. p

If preferred, the metal roof sheets, 23',- may be provided with lining sheets, 39, of any suitable insulating material, as indicated in Fig. 6. Y

The running board saddles or brackets, 40, are preferably supported directly upon the carlines-, and may be fastened by any convenient means, as by rivets or bolts, di-

rectly to the carline cap, 22, as shown. The

running board, 41, may then be conveniently bolted to said saddles, 40, and allthe weight is carried directly by the carlines.

At each end of the car, the running board is providedwith a transverse extension, 43,

running down to the eaves of the car, and

for supporting the lower end of this extension, I provide a-bracket'member, 42, which may be secured or supported at one end upon the end plate of the car, but having its other end extending to, and secured to,'the cap of the first carline, so that the entire,weight is carried by the carline andend plates and not by the roof sheets. The usual hand hold,

44, may be mounted upon the running board extension.

Ventilating openings, 45, may be formed through the walls' of the U shaped body of the carline, 20, to permit a free circulation of airfrom the interior of the car through thechannels in the carlines, and,-as these are open to the outer atmosphere 'at the eaves of .the car and also through openings, 31, into the ridge gutter, 30, and out through vent openings, .34, a thorough ventilation system is provided sothat the so-called sweating or collection of moisture upon the interior surfaces of the carlines and roof sheets is prevented, and the accumulation of rust thereby avoided.

It will now be seen that 85 adapted to be riveted tothe flanges of sa d a roof construction is simple, but durable, strong, and flexible; that it can be readily constructed of the usual standard sections and parts without requiring skilled or ex-' pensive labor; that it provides a complete system of drainage and ventilation: and that the weight of the running board and its extensions, with all brackets and other outside parts, is carried upon the carlines.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. In a car roof, the combination of a metal carline composed of a lower U shaped section having a drain channel, and a cap member of a T'section covering said channel and having its web extending down into the channel of the lower member and rigidly secured to the side walls thereof, leaving a clear space for drainage at the bottom of said channel, and metal roofing sheets having their edges slidably supported on the lower carline member and beneath the flange of the cap member, and adapted to drain into said channel.
